Modified polytetrafluoroethylene wire enamel and preparation method thereof

Abstract

The invention discloses modified polytetrafluoroethylene wire enamel which is characterized by being prepared from raw materials in parts by weight (kilogram) as follows: 13-17 parts of dimethylaminoethyl methacrylate, 5-8 parts of benzoyl peroxide, 1-2 parts of triethanolamine, 5-8 parts of ethanediol, 12-15 parts of nylon 12, 10-12 parts of neopentyl glycol, 1-2 parts of polytetrafluoroethylene, 5-7 parts of beryllium oxide, 1-2 parts of dibutyltin dilaurate, 2-4 parts of aluminum hydroxide, 12-14 parts of polypropylene random copolymers, 2-4 parts of nano pottery clay, 7-9 parts of an assistant, 100-120 parts of m, p-cresol and 70-80 parts of xylene. The modified polytetrafluoroethylene wire enamel has good adhesive force, high flexibility and excellent heat resistance, elasticity, toughness resistance, voltage resistance and solvent resistance.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a polytetrafluoroethylene modified wire enamel and a preparation method thereof. Background technique [0002] Enameled wire is a kind of electrical material. It processes a thin layer of high-strength insulating layer on the surface of a round copper wire to insulate it from the outside world. According to the specifications, it can be processed into a wool thread thinner than a hair, and a yarn-covered thread as thick as a thumb. Enameled wire has good insulation effect and waterproof ability. It is widely used in electrical appliances, such as motors, generators, water pumps, electromagnets, electric welding machines, household appliances, wireless communications, speakers, telegraphs, transformers, etc. Enameled wire enamel is a necessary insulating material for the production of enameled wire. Enameled wire enamel requires good adhesion, mechanical strength, insulation performance, heat re...

AI Technical Summary

Problems solved by technology

Enameled wire enamel is a necessary insulating material for the production of enameled wire. Enameled wire enamel requires good adhesion, mechanical strength, insulation performance, heat resistance, wear resistance, salt spray resistance and harsh environment resistance, etc., but ordinary wire enamel has resistance to It is difficult to meet the requirements of different environments due to problems such as thermal resistance, poor wear resistance, insufficient strength, and heat resistance below 120°C.
